Development of Pavement Structural Analysis Tool for Iowa Local Roads TR-762

The primary objective of this research would be to develop an easy-to-use pavement structural analysis tool (for Iowa county roads) for use by county engineers in routine pavement analysis/design/asset management practices to provide effective communication regarding pavement needs both to the public and to elected officials. To accomplish this primary objective, the pavement structural analysis tool would require the following specific features: (1) Analyzing capacity for a multi-layer pavement system in which each lift has a unique age, thickness, material, physical condition, modulus, and prior traffic carriage impacts; (2) No required complex input preparation; (3) Real-time computation capability; and (4) End-user friendliness with respect to inputs and outputs.
